Fetching seller product catalog produces error: Failed to process response

On fetching the seller's product catalog, sometimes the API generates an error saying "Failed to process response". It does not happen all the time, but once in a while this error is generated:

{"metadata":{"requestId":"059180d9-xxxx-xxxx-xxxx-xxxxxa9ef0ff","clientId":"xxxx@xxxxx.com","message":"Failed to process response","responseTime":148,"requestedURI":"GET /products/search"}}

The response code is 500. This failed on successive tries on Aug 4th, but works now.

Could you please look into what went wrong? I will be glad to hear that the issue was already resolved on your end, and isn't likely to happen again. Please confirm
